Definitions

  • the present invention relates to a device for harvesting stalk-like stem crops, having a number of picking units arranged side by side on the frame of the device, each of which has picking plates that laterally delimit a picking gap and picking rotors located beneath said picking plates, said device also having conveying units embodied as continuous conveyors driven in circulation, which are assigned to the respective picking units, are arranged on opposite sides above a picking gap, and have carrier elements attached to the circulating elements, and a transverse conveying device located downstream of the conveying units.
  • the devices of interest here for harvesting stalk-like stem crops are installed on combine harvesters as corn picker heads for harvesting corn grain.
  • the corn picker heads the ears of corn are separated from the stalks, the stalks and leaves are discarded onto the ground, and the picked ears of corn are delivered to the combine harvester for threshing.
  • the plant stalks are pulled downward by at least one picking rotor once the plant stalk has entered the picking gap, which is delimited by at least one laterally disposed picking plate.
  • an ear of corn attached to the corn stalk reaches the picking gap, it becomes caught on the picking plate(s), whereas the stalk is carried further downward because it is wider than the picking gap. This causes the ear of corn to tear away from the stalk.
  • the carrier elements circulating continuously with the continuous conveyors for example chain conveyors or belt conveyors, then catch the separated ears of corn and feed them to the transverse auger, which collects the separated ears of corn at the center of the device and delivers them rearward to the combine harvester.
  • Two continuous conveyors having conveyor chains or belts, for example, are typically used in a picking unit, and are arranged in a plane above the picking plates and on both sides of the picking gap. The axes of rotation of the deflecting wheels are parallel to one another.
  • conveying elements of a continuous conveyor these are understood to represent any technical means that are capable of circulating and thereby moving carrier elements along the picking gaps.
  • the continuous conveyors each circulate on at least one front and one rear deflecting wheel.
  • the purpose of the continuous conveyors is not only to transport the cornstalks out of the area of the picking gap, but also to pick up and lift cornstalks lying in the field in the area of the front deflecting wheel, and enable these laid cornstalks to enter the picking gap.
  • the position of the lowest point on the continuous conveyor is determined by the spatial positioning of the front deflecting wheel since, due to the circular shape of the deflecting wheel, the continuous conveyor reaches its lowest point at only one location as it travels around the deflecting wheel.
  • the diameter of the deflecting wheel determines the distance of the lowest point from the center of the picking gap.
  • the devices known from the prior art are designed for use with 30-inch row widths of stalk-like stem crop, and function satisfactorily with flat-lying deflecting wheels.
  • the continuous conveyors themselves are disposed sloping upward from the field toward the rear, to allow the picking rotors to be positioned beneath them.
  • the axes of rotation of the deflecting wheels are not set at an angle transversely to the picking gap. In this arrangement, the foremost point on the deflecting wheel determines the lowest position of the continuous conveyor.
  • U.S. Pat. Nos. 5,884,464 and 5,924,269 propose staggering the heights of the continuous conveyors and allowing the continuous conveyors to overlap on the sides facing away from the picking gaps, in order to save on overall width.
  • the higher positioning of the continuous conveyors results in a less effective intake of laid corn.
  • the continuous conveyors must be positioned at a very steep angle.
  • the covering hoods then protrude substantially higher between the picking gaps because the overall width of the continuous conveyors has remained unchanged.
  • the tall covering hoods impede the flow of harvested crop material.
  • the object of the present invention is to find an arrangement for the continuous conveyors that will result in a decreased overall width without significantly impairing the intake of laid corn.
  • the object is achieved for a device of the type in question, in that the axes of rotation of front deflecting wheels of the continuous conveyors are positioned obliquely at an angle transversely to the working width of the device and to the picking plane, which is defined by the mutually facing front edges of the picking plates assigned to a picking gap, such that the imaginary extensions of the axes of rotation intersect above the picking plates at a distance from the picking plane, and the carrier elements formed on the continuous conveyors are for their part positioned upward at an angle to the axis of rotation of the deflecting wheels.
  • the obliquely angled positioning of the axes of rotation of the deflecting wheels transversely to the working width of the device reduces the width requirement of the continuous conveyors across the overall width of the device.
  • the overall width is reduced further by the upward positioning of the carrier elements of the two continuous conveyors.
  • the device can be used for 15-inch row widths.
  • the imaginary extensions of the axes of rotation do not actually need to be long enough to intersect above the picking gap at a distance from the picking plane; rather, the axes of rotation need only to be long enough to support the deflecting wheels of the deflecting conveyors. Otherwise they would impede the flow of material.
  • the oblique positioning of the deflecting wheels transversely to the working width of the device and to the picking plane makes it unnecessary, in particular, to raise the picking plane and/or to position the continuous conveyors themselves at a higher level.
  • the foremost deflection point of the deflecting wheels of the continuous conveyors therefore remains very low and close to the ground.
  • the carrier elements traveling around the front deflecting wheels traverse a spatial movement path in which they first travel from a higher level toward the ground down to the front deflection point, and after passing the front deflection point they move back upward again, and in so doing, due to the upwardly offset position of the carrier elements, they are better able to pick up and carry along stem crop material lying close to the ground.
  • this specification is understood as the orientation of the device toward the standing crop material.
  • the front is the area with which the device is moved into the standing crop
  • the rear is the direction in which the crop material gathered by the device is delivered to the combine harvester.
  • the axes of rotation of the deflecting wheels of the continuous conveyors are positioned obliquely at an angle ⁇ to the picking plane, transversely to the working width of the device and to the picking plane to the picking plane, which is defined by the mutually facing front edges of the picking plates assigned to a picking gap, and the carrier elements located on the continuous conveyors are positioned obliquely at an angle ⁇ to the circulating plane defined by the deflecting wheels, the angle ⁇ being selected such that the carrier elements circulate along a boundary curve in which, in their removal direction, the lower edge of said carrier elements is aligned in a plane parallel to the picking plane.
  • the distribution of the setting angles between the oblique positioning of the axes of rotation and the offsetting of the carrier elements transversely to the working width of the device and to the picking plane results in crop-friendly transitions in the areas of transition to other machine parts, and in the optimal utilization of installation space.
  • the covering hoods between the intake gaps do not protrude too high, but there is still sufficient space for the intake of crop material, for the picking operation, and for transporting the picked ears of corn out of the area.
  • the plane-parallel circulation of the carrier elements with their lower edges facing the picking plane enables crop material lying on the picking plates to be cleanly and reliably caught and transported away rearward. Even small individual grains are not left on the picking plates, and are instead carried away. Also avoided is grain breakage, which might otherwise occur from grains becoming squeezed between the carrier elements and the surface of the picking plates during transport, and thereby damaged.
  • angles ⁇ and ⁇ are each approximately or precisely 45°. A variation of plus or minus 5° is considered non-critical. With these angular dimensions, as each of the carrier elements travels forward during a revolution, its lower edge extends upward at precisely or roughly a right angle to the lower edge of the carrier element that is returning in the removal direction. In this returning position, the carrier elements require only a small width dimension, because they are aligned with their conveying width facing upward, thereby further reducing the possible distance between picking rows in a device.
  • a plurality of deflecting wheels are arranged offset from one another laterally and longitudinally along the device, wherein for each continuous conveyor, the foremost deflecting wheel is located a greater lateral distance from the longitudinal center axis of the intake gap than the deflecting wheel located further toward the rear, and the plurality of deflecting wheels of the continuous conveyors assigned to a picking gap delimit a roughly V-shaped intake opening, in portions of which the mutually opposing continuous conveyors have a linear profile.
  • the circulating path for the continuous conveyors created between the two front deflecting wheels does not travel upward with the carrier elements immediately after the foremost deflecting wheel, and instead travels sideways initially, in a roughly or precisely horizontal plane.
  • a continuous conveyor that initially travels roughly horizontally close to the ground in the intake region, extending in roughly a funnel shape from the two sides of the picking gap, enables laid corn that is still active for transport to be picked up from the ground and transported into the area of the picking gap, even when the crop material is in very narrow rows.
  • the axes of rotation of the rear deflecting wheels of the continuous conveyors are positioned obliquely at an angle transversely to the working width of the device and to the picking plane, such that the imaginary extensions of said axes of rotation intersect above at a distance from the picking plane.
  • the chains or belts of the continuous conveyors are not staggered, or are staggered only slightly during circulation.
  • the axes of rotation of the rear deflecting wheels of the continuous conveyors are positioned at an angle of precisely or approximately 45° to the picking plane.
  • this also results in the advantage that the necessarily uniform distribution of the setting angles between the oblique positioning of the axes of rotation and the offsetting of the carrier elements results in crop-friendly transitions in the areas of transition to other machine parts, and that the installation space in the removal region of the picking gap is optimally utilized.
  • the covering hoods between the intake gaps do not protrude too high in the rear area of the picking gap.
  • a deviation of the angle by plus or minus 5° is non-critical, as it results in only an insignificant increase in overall width.
  • the carrier elements pass over a threshold at the rear end of the picking gap, which threshold forms the transition from the picking plates to the trough of the transverse conveying device.
  • the offset configuration of the carrier elements and the oblique positioning of the axes of rotation of the rear deflecting wheels result in this area in an upwardly directed movement of the carrier elements, which causes the crop material transported by said carrier elements to separate more easily from them and slide obliquely downward into the active region of the transverse auger as the transverse conveying device, while the carrier element moves upward away from the harvested material. This reduces the risk of clogging and of material accumulating in the area of transition, where the carrier elements reach the covering hood, beneath which they turn and move toward the front again.
  • At least one picking rotor has a plurality of cutting disks, distributed over its length and supported by the shaft of the picking rotor, said cutting disks projecting radially beyond the cylindrical body of said picking rotor and extending up to or into the boundary circle of the adjacent picking rotor.
  • a cutting device integrated into the picking rotors for chopping up stalks and leaf debris that have been pulled down by the picking rotors saves on installation space, which is particularly scarce with very narrow row widths.
  • drive shafts of side-by-side rear deflecting wheels are covered up to the transverse conveying device by a cover plate, which extends upward from the threshold up to the plane of rotation of the adjacent rear deflecting wheels.
  • the cover plate may be formed from a single part or multiple parts.
  • the cover plate prevents crop material from being carried along by the drive shafts and/or by the rear deflecting wheels and being wound up into a thick layer of material. This is advantageous particularly because the carrier elements moving upward in the region of the rear deflecting wheels might carry crop material along and transport it upward in the transition area.
  • material being conveyed sideways by the transverse conveying device might reach the area of the drive shafts. The cover plate prevents this.
  • the continuous conveyors and picking rotors assigned to a picking gap are driven by a common series gearbox, wherein the series gearbox for driving each continuous conveyor has a first gear stage from a main drive shaft to an intermediate shaft and a second gear stage from the intermediate shaft to the shaft on which the rear deflecting wheel of the continuous conveyor is mounted for conjoint rotation, and wherein the first gear stage is embodied as an angular gear, so that the intermediate shaft is not parallel to the main drive shaft.
  • the series gearbox can be used in modular form in a device. For instance, 6, 8 or 10 series gearboxes can be mounted side by side on the frame, depending on whether the device is configured widthwise for a harvesting capacity of 6, 8 or 10 rows.
  • the series gearbox is approximately Y-shaped, with the two branches in which the shaft for driving the rear deflecting wheel is located extending obliquely upward and projecting laterally somewhat.
  • This enables the series gearbox to be configured as narrow enough that, despite a main drive shaft extending centrally through said gearbox, a single series gearbox can contain all the outputs required for the continuous conveyors and picking rotors, even with 15-inch row widths.
  • a separate output for a chopping device can be dispensed with, thereby further simplifying the series gearbox.
  • a shaft connection for continuing the main drive shaft is located between adjacent series gearboxes.
  • the angled positioning of the outputs for the rear deflecting wheels of the continuous conveyors creates installation space beneath said outputs, in which a shaft connection for continuing the main drive shaft can be located between the adjacent series gearboxes.
  • the series gearboxes can thus be connected to one another on the frame, with the interposition of a shaft connection therebetween. For maintenance and repair work, the series gearboxes can simply be removed in series from the frame as needed.
  • an overload clutch is located in the series gearbox between the main drive shaft and the first angular gear and/or the second angular gear.
  • Known devices such as a cam clutch, a ball clutch, a shear pin clutch or the like, may be used as overload clutches. It is advantageous for one or both overload clutches to be housed centrally and protected in the narrow installation space between the 15-inch row width and within the common gearbox housing.
  • At least two picking rotors arranged along the picking gap are located below the picking plates, the boundary circles of said picking rotors overlapping at least in certain areas.
  • stationary or rotating blades are arranged spaced from one another along the length of the picking gap and extending into the boundary circles of the picking rotors.
  • the stationary or rotating blades very efficiently shred the residual plant material that is pulled downward through the picking gap.
  • the use of stationary or rotating blades that extend into the boundary circles of the picking rotors enables high forward travel speeds during harvesting, while good shredding capacity is maintained.

  • Carrier elements 18 are mounted rigidly on the chains or belts of continuous conveyors 22 .
  • continuous conveyors 22 are driven such that carrier elements 18 travel along picking plates 12 and picking gap 14 to the rear, where they are deflected by the respective rear deflecting wheel 26 to travel forward again, extending upward, back to the front deflecting wheel 26 , where they are again deflected, allowing them to pick up more crop material and travel rearward again over picking plates 12 .

  • the angular positioning of the axes of rotation 24 of deflecting wheels 26 gives the continuous conveyors a relatively narrow overall width B as viewed over the width of device 2 , despite a considerably wider effective overall width B(e).
  • This design gives the carrier elements 18 a range R, which leaves sufficient space in the area of the picking plate plane 28 for the ears of corn to be separated cleanly from the stalks, but also enables the ears of corn to be effectively transported away afterward by the carrier elements 18 .
  • carrier elements 18 are connected rigidly to the chain or the belt of the continuous conveyor 22
  • carrier elements 18 may also be connected to the associated chain or the associated belt via a pivot joint, allowing the carrier elements 18 to be placed, by way of gravity and/or motion links, in a position relative to the chain or the belt and relative to the picking plates 12 with the picking gap 14 , that is favorable for a specific function.

  • the conveying channel which is delimited by the side walls of the covering hoods 20 and the continuous conveyors 22 , which then extend converging with one another toward the rear, is narrowed.
  • the rear deflecting wheel is set at a steeper angle, the conveying channel will be wider in this area, however covering hood 20 will also project higher.
  • the angled position of the axes of rotation 24 of 45° from picking plane 28 in the exemplary embodiment and the offset of carrier elements 18 by 45° from the axes of rotation 24 in the exemplary embodiment result in an effective compromise between an optimally space-saving design and a conveying channel of sufficient width above picking gap 14 .
